  Border technique: clip-path clips CSS borders, so we use two layers:
    - outer .folder_N: position:fixed sizing, drop-shadow filter
      (filter sees the clipped inner = renders as 1px black border)
    - inner .folder-body: clip-path + background color
  This is the only reliable CSS-only way to border a clip-path shape.
